Which Boveda should I use for bow storage?
Use Boveda B49 Size 8 packets in bow tubes and cases.
B49 Size 8 packets are sized to fit in bow tubes and cases. (Each packet measures 2.75"/7 cm x 2.5"/6.35 cm.)
ALWAYS insert the packet into a Mini Holder before using in your case.
DO NOT use Boveda Size 8 for guitars or other larger instruments. These smaller packets do not contain enough formula to properly maintain humidity levels in large instrument cases. For guitars and other instruments, use B49 Standard Refills.
